Former Cuban President Fidel Castro is reportedly accusing Sen. John McCain (R-Ariz.) and Israel of conspiring to create the Islamic State in Iraq and Syria (ISIS).

In a column written for Cuban state media, the former communist leader attacked McCain as Israel’s “most unconditional ally.”

Castro, 88, alleged McCain “together with [Mossad, conspired] in the creation of the Islamic State, which today controls a considerable and vital portion of Iraq and reportedly one-third of Syria as well.”
